I've failed to watch the weather to notice that the temperatures in Indy were going to be in the high-70's all week - so my beer has been fermenting at about 76 degrees for the past 12+ hours. This morning I put it in a swamp cooler with some ice packs to try to bring that temperature down. Is my beer to taste "off?" Oh yeah, it's a pumpkin beer.

How long into the fermentation was it when the temp was up in the 70s? Also, what strain of yeast did you use?

WYeast 1728, possibly 12 hours. It started fermenting while I was at work yesterday and I failed to look at the temperature before leaving. When I got home yesterday is when I noticed it and put it water.

Edit - WYeast says the temp range is 55-75F

I imagine you'll have some fruity Esters, probably not what you want with the spiciness of a pumpkin beer... Just let it ferment for a little longer than normal at cooler temps, hopefully the yeast will clean it up a bit.

You also might have some fussel alcohols, the yeast will hopefully clean some of then up too, and depending on the abv they might not be noticeable.

So the short answer is, just give the beer a little longer than normal to clean up, and who knows, it could turn out to be your favorite beer ever.

Also, the reason i asked how long it had been fermenting is because temps are most important during the first stages of fermentation. It's when the yeast are the most aggressive and they are expelling lots of energy in the form of heat.

if the ambient temp was 75, your beer was probably fermenting in the high 80s at least.

But now that it's done, do what you can, and RDWHAHB

Right on, thanks for your help! This is only my 6th batch of beer to make, so I'm really starting to pay more attention to the process in hopes of more consistent beers. Just another lesson to put down on the notebook of "don't forget to" haha

I just asked my wife to check the beer and she said it's down to 70, yay!

Looks like the water bath did the trick - 66-68F all night. Got the ice packs ready for today, 80 in Indy.

Nice. Let us know how it turns out. Swamp coolers are a wonderful thing (until you get a chest freeze and a temp controller)
